Consider a simple Brayton cycle using air as the working fluid with properties assumed constant and evaluated at room temperature (300 K). Conditions at the compressor inlet are T1 = 25°C and P1 = 200 kPa. The pressure ratio is 11 and maximum cycle temperature is 750°C. Answer the following (a) Compute the back?work ratio and cycle efficiency assuming both the turbine and compressor are isentropic (b) Compute the same quantities assuming only the turbine is isentropic while the compressor has an isentropic efficiency of 75% (c) Compute the same quantities assuming only the compressor is isentropic while the turbine has an isentropic efficiency of 75%

Please show all work, assume ideal gas and cold air assumptions and please write legible. Thanks
